VALVE FOR WATER-TANK SUPPLY.

SPECIFICATION forming part of Letters Patent No. 692,983, dated February 11, 1902. Application filed May 7. 15501. Serial No. 59,083. (No model.)

To all whom, it may concern.-

Be it known that l, WILLIAM E. CLARK, a citizen of the United States of America, and a resident of Springfield, in the county of Hampden and State of Massachusetts, have invented certain new and useful Improvements in` Valves for Water-Tank Supply, ofv whichthe following is a full, clear, and exact description. Y

This invention relates to improvements in valve mechanism Vfor controlling the supply of water to water-closet tanks and other receptacles where ball-cocks are ordinarily employed.

The object of this invention is to provide a new and improved valve mechanism which is of extreme simplicity of construction and cheapness of manufacture and which is eicient in operation, with an avoidance of hissing, hammering, or other objectionable noises and which is of such durability as to withstand for an unusually longtime without-impairment or the necessity of packing or adjustment.

The invention consists in the combination, with an upstanding plug or member externally tapered, having a longitudinal passage therein in communication with the watersupply and having one or more outwardlyleading ways extending from the longitudinal passage to the tapered external periphery of said member, of a shell the opening in which is downwardly flaring and adapted to have a closing fit about and to be movable axially relatively to the said upstanding plug or member, with means for imparting thereto automaticallyits endwise opening movement, and preferably in connection with this specified construction of valve mechanism the said shell is formed with an opening or chamber therein at the portion thereof which is above the upper end of the said upstanding tapered member, from which chambered portion are one or more outwardly-extending passages, ports, or waterways.

An exemplication of my invention is illustrated in the accompanying drawing, in which the figure shows the valve mechanism constructed in the preferred way in substantially central Vertical section.

In the drawing, A represents a water-closet tank of the ordinary kind, within which is lo- Y cated to have a seating or rest on the bottom of the tank the casting or appliance B, the same comprising a base member 10, with the horizontal passage 12 therein connected with the upstanding and upwardly-opening coupling-hub 13 and also the upstanding plug or member C, which is externally upwardly tapered, as shown, and which has the internal axial or longitudinal passage 14 connected with the aforesaid horizontal passage 10, said plug being, moreover, constructed with the upper end-closing wall 15 and suitably therebelow with the outwardly-extending ports or waterways ce, one or more.

D represents the down wardly-aring inverted shell, the tapered opening therein fitting to close about the external periphery of the aforementioned upstanding tapered plug, this shell also having the chamber b in the upper portion thereof above the upper end of the plug, from which chamber lead outwardly the ports or waterways d. The said part D is constructed with the upwardly-extended hub or boss f, havin g the screw-threaded socket therein, in which screw engages the valve-operating rod or stem g.

The peripheral surface of the plug C and the internal surface of the downwardly-Haring shell are smoothly ground to nicely fit one to the other.

h represents a coupling having a flanged base or footpiece 16, which is adapted to rest on the upper edge of the wall of the tank and to be secured thereupon by the screw or screws 16a. The said coupling at its horizontallyextended end portion is adapted to receive connection with the surface-pipe of the water system, and the downwardly-turned limb h2 of said coupling receives by screw-thread engagement the connection therewith of the upper end of the pipe fr', the lower end of which has a screw-thread connection in the upwardly-opening socketed hub 13 of the aforementioned hollow base portion 10 of the valve mechanism.

The confinement of the coupling h bythe screw 1G through the medium of the pipe t' serves to hold the upstanding valve-plug and its base firmly at rest on the bottom of the tank. The said coupling h is constructed with the bracket-arm 17, to which is pivotally hung the lever-arm G, which carries the ball- IOO oat F, and to the extremity of this lever-arm which is beyond the pivot 18 and farthest from the float the upper end of the valvestem g is connected at 19.

The parts shown in full lines and described are for the provision of what is termed a f top supply, but the inlet of water may be from beneath, as indicated by the dotted-line representation at i2.

The water in the tank having been withdrawn and the level thereof lowered, the descending float will insure a lifting of the stem g and the shell D, opening the waterways a a, so that the Water from the inlet may flow from the longitudinal passage in the upstanding externally-tapered plug radially and for communication and entrance to the tank, a portion of the water being forced in a downward direction to emerge at the lower end of the inverted shell, while a portion thereof passes in an upward direction int-o the chamber b, and thence passes therefrom radially through the ports or ways d d into the tank.

The hood or bell-shaped casing E serves as a delector, causing the water issuing through the valve necessarily to have a downward course, and preventing, however low the Water in the tank may be, the incoming water from being thrown upwardly, the desirability of which is manifest.

Having thus described my invention, what I claim, and desire to secure by Letters Patent, is

1. The combination with an upstanding plug or member externally tapered having a longitudinal passage therein in communication with the water-supply,and having one or more outwardly-leading ways extending from the longitudinal passage to the tapered external periphery of said member, of a shell, the open-V outwardly-leading Ways extending from the longitudinal passage to the tapered external periphery of said member, of a shell, the opening in which is downwardly flaring and adapted to have a closing lit about, and to be movable axially relatively to the said upstanding plug or member, with means for imparting thereto automatically its. endwise opening movement, the said shell being formed with an opening or chamber therein at the portion thereof which is beyond the end of the tapered member, and having one or more waterways extending outwardly from said chamber.

3. The combination with a valve, one member of which consists of an axially vertical part supported above a hollow base, which is constructed with an upwardly-opening socketed member 13, the coupling h having the footpiece adapted to be secured to the top of the tank, and having the downwardly-turned limb h2, the pipe iconnected to said limb, and to said portion 13, and serving as a medium between the coupling and the base member of the Valve, for confining the latter against the bottom ot' the tank, the secondary member of the valve relatively movable to and away from the first-named valve member, and means for automatically moving it.

4. In a valve mechanism for tanks, in combination, theupstanding tapered plug C having the vertical passage 14, radial ways ct a, and upper end-closing wall 15, and the supporting-base therefor having the horizontal passage 12 and upstandin g threaded socketed portion 18, the coupling h, having footpiece 16 and downwardly-turned limb h2, the pipesection i connected to said limb h2 and said part 13, the bracket-arm 17 supported by the coupling, the float and its lever-arm pivotally connected to the bracket, the valve-stem to which said lever-arm is connected, and the donwnwardly-arin g shell adapted to t about the tapered plug, carried at the lower end of said stem, substantially as described.

Signed by me at Springfield, Massachusetts, this 4th day of May, 1901.
